Polyethylenimine Facilitated Ethyl Cellulose for Hexavalent Chromium Removal with a Wide pH Range
Ethyl cellulose (EC) composites modified with 20.0 wt % polyethylenimine (PEI) (PEI/ECs) demonstrated effective hexavalent chromium, [Cr(VI)], removal from solutions with a wide pH range. For example, 4.0 mg/L Cr(VI) solution with a pH below 3.0 was completely purified by 3.0 g/L PEI/ECs within 5 min, much faster than the as-received EC (2 h) and activate...

Effects of Ethyl Cellulose on the Crystallization and Mechanical Properties of Poly(β-hydroxybutyrate)
International Journal of Biological Macromolecules, 2016,88C, 120-129.
ABSTRACT:
Ethyl
cellulose (EC) was blended with poly(β-hydroxybutyrate)
(PHB), aiming at controlling crystallization and mechanical properties of PHB. The obtained PHB/EC blend is an immiscible system,
and the discrete EC phase behaves dual characteristics in the PHB matrix, as
the viscoelastic droplets dur...

Quantitative Dependence of Crystallinity on Degree of Branching for Hyperbranched Poly[3-ethyl-3-(hydroxymethyl)oxetane]
A series of hyperbranched poly[3-ethyl-3-(hydroxymethyl)oxetane]
samples with various degrees of branching (DB) were adopted to investigate the
relationship between crystallinity and DB. The relative degree of crystallization
(DC) and DB were determined by x-ray diffraction (XRD) and 13C nuclear
magnetic resonance (13C-NMR) measurements, respectively. The corresponding
plot of DC versus DB shows q...

Self-assembly of ethyl cellulose-graft-polystyrene copolymers in acetone
The self-assembly of the dense graft copolymers ethyl cellulose-graft-polystyrene (EC-g-PS) in acetone was investigated by using dynamic light scattering (DLS), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). It was found that EC-g-PS copolymers can self-assemble into spherical micelles in acetone. The micelles' size increases with increasing the copolymer conce...

Synthesis, self-assembly, and thermosensitive properties of ethyl cellulose-g-P(PEGMA) amphiphilic copolymers
Ethyl cellulose graft poly(poly(ethylene glycol) methyl ether methacrylate) (EC-g-P(PEGMA)) amphiphilic copolymers were synthesized via atom transfer radical polymerization (ATRP) and characterized by FTIR, 1H NMR, and gel permeation chromatography. Reaction kinetics analysis indicated that the graft copolymerization is living and controllable. The self-assembly and thermosensitive property of the...

NUCLEIC ACID NANOCARRIERS BASED ON ALKYLMETHACRYLIC ACID COPOLYMERS
PEG-b-poly (alkyl (meth) acrylate-co-methacrylic acid)s are diblock copolymers which can self-assemble in aqueous media in a pH-dependent manner to form polymeric micellar structures that can be exploited for the oral delivery of drugs.

Effect of carbon chain length of monocarboxylic acids on lower critical solution temperature of poly(2-ethyl-2-oxazoline)
The temperature induced phase transition of poly(2-ethyl-2-oxazoline) (PEOxz) aqueous solution undermixing with a series of small carboxylic acids has been studied by turbidity measurements and laser lightscattering. It has been found that ...
